Exploring the concept of speed. Students will realise that speed is made up of two measurements, one of distance travelled, and one of time taken. These two measurements can be used to calculate speed, which can be converted to different units.
L.I. Students will be able to 1. use appropriate scales, devices & metric units for length, area, volume & capacity, weight (mass), temperature, angle and time. 2. convert between metric units, using whole numbers and commonly used decimals. 3. use a range of multiplicative strategies when operating on whole numbers.
S.C. We will
calculate speed from measured distance and time
solve multiplication problems using doubling and halving strategies
use know multiplication facts to solve multiplication problems

My estimation for running km per hour.
14 kmp.
After the test I have discovered that I can run 14 kmp.
Time taken over 100m 16 secs
15.1 kmph
6.6 mps
31.3.11
1. What speed can a student travel by bike.
estimation 14km
real 18.75kmph
2. What speed can a student travel per second.
estimation 7mps
real 5.2mps
I now know how to measure speeds in km and mps.
100m
Men 9.58 seconds Usain Bolt
kmph 44 kmph
mps 10.4 mps
Women 10.49 seconds Florence Griffth-Joyer
kmph 35 kmph
mps 9.5 mps
200m
Men 19.19 seconds Usain Bolt
kmph 28 kmph
mps 10.4 mps
